Here are some key runtime characteristics:\\n\\n1. Decentralization: Blockchain adopts a peer-to-peer network architecture, where data is not stored and managed by a central node, but is distributed across multiple nodes throughout the network, reducing the risk of single-point failure.\\n\\n2. Data cannot be tampered with: Blockchain uses encryption algorithms (such as SHA-256) to ensure the security of data, once the data is recorded in a block, it is difficult to tamper with. This is because each block contains the hash value of the previous block, and modifying a block would result in a mismatch in the hash values, making the tampering  evident.\\n\\n3. Transaction immutability: Once a transaction is recorded in a block, it cannot be altered or deleted. This ensures that the transaction history is permanent and"}]}],"pr":"a2b6d65ebfbe086525ddc4e180b7af224456295a7fda6d1eb84cfbea957b6592"}
